Another insider said that Moore is still "humiliated" by Kutcher's cheating, reported the magazine.

"What was humiliating was having her husband cheat on her in such a public way," said the source close to the situation. "But once that happened, she has not looked back."

Moreover, a third source speaking to People defended the actress.

"As hard as it has been, despite the depression of going through a divorce, [Demi] came through it," noted the insider.

Moore and Kutcher were married in 2005 before their split six years later. Their relationship stirred controversy, as Moore is 16 years older than Kutcher.

The actor starred on "That 70's Show" alongside Kunis from 1998 to 2006.

Past reports have also claimed that Moore was hurt over Kutcher's new romance with Kunis as the two have been longtime friends.

"[Demi's] not psyched about Ashton and Mila," said one source close to Moore, according to Us Weekly. "She was always insecure over the course of her marriage so yeah, it's hurtful that he's with someone he knew the whole time he was with her."
